Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed January 17, 1912. Serial No. 671,576.

To all whom it may concern:

Be it known that I, EDWARD L. PEISAR, a citizen of the United States,residing at Glenwood Springs, in the county of Garfield and State ofColorado, have invented certain new and useful Improvements in Water-Elevating Apparatus, of which the following is a specification.

This invention relates to a water elevating apparatus or pump forraising water from a source of supply to a higher level for domestic orother uses or for irrigating land which can not be irrigated by surfacegravity in the usual way.

The primary objectof the invention is to provide simple and effectivepumping mechanism for raising water from a cistern or other reservoir tothe desired elevation for service, which mechanism is adapted to beoperated by the force of gravity of bodies of water obtained from aflowing source of supply.

A further object of the invention is to provide a duplex ordouble-acting pumping mechanism of this character, the pumping elementsof which will be automatically and alternately operated by bodies ofwater from one and the same source of supply.

The invention consists of the features of construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the 'accompanying drawings, in which Figure 1 is a sideelevation of a pumping apparatus embodying my invention, the reservoirappearing in section and the walkingbeam or lever at the limit of itsworking motion in one direction. Fig. 2 is a similar view with thewalking-beam or lever shown partially in longitudinal section and at thelimit of its opposite working motion. Fig. 3 is a vertical transversesection through the apparatus. Fig. a is a perspective view of one ofthe buckets and its gate or valve.

Referring to the drawings, 1 designates a cistern or reservoir having adepressed floor or platform 2 arranged within its mouth and providedwith openings 3 and 4c for the flow of water to the body of saidcistern. This or any other suitable type of reservoir may be employed.Above the mouth of the cistern or reservoir is arranged a flume orcondoctor 5 for supplying a stream of water from a suitable primarysource.

Mounted upon the floor or platform 2 at a point midway between theopenings 3 and 4 are spaced parallel brackets or standards 6 carrying atransverse pivot pin or bolt 7. Pivotally engaging this pin or bolt arespaced fulcrum plates 8 fixed to and depending from the center of awalking-beam or lever 9, which is thus mounted to rock or tilt in avertical plane. The oppositely extending arms 10 and 11 of thewalking-beam or lever are in the form of open-topped troughs orreceptacles, each having an inner receiving chamber or compartment 12and an outer discharge chamber, bucket or compartment 18. The bucket 18depends below the bottom 14; of the chamber 12 and has the upper portionof its inner wall sloping upwardly and inwardly, as at 15, andprojecting inwardly beneath the wall 14 to form a flaring entrance tothe bucket, into which the outer end of said wall let partially eX-tends in the form of a ledge or shelf 16. Each bracket is open at itsouter end for the discharge of water therefrom and is provided withguideways 17. In these guideways is fitted to slide a gravity-closinggate or valve 18 provided with a depending contact pin 19 adapted oncontact with the floor or platform 2 to force said gate or valve open. Atransverse partition 20 is disposed between and separates the twochambers 12. The upper edges of the side walls of the arms 10 and 11slope outward and downward, thus making each chamber 12 of maximum depthat its inner end.

Supported by the platform 2 is a pair of pump cylinders 21 and 22 thepiston rods 23 and 24 of which are pivotally coupled to wrist-pins 25and 26 and arranged on opposite sides of the fulcrum pin 7, whereby thepump pistons are adapted to be alternately operated on their suction anddischarge strokes by the reverse rocking motions of the walking-beam orlever. The suction ports of the cylinders communicate with dependingconducting pipes 27 and 28, while the outlets 29 and 30 of saidcylinders are connected by a union 31 provided with an air-pressurechamber or head 82 communicating with a delivery or stand pipe 33leading to the elevation to which the water is to be forced. Checkvalves 34, 35 and 36 are provided in the above-described connections foran obvious purpose.

water from the flume 5. When a suflicient quantity of water to overcomethe weigli't of the arm 11 and the resistance of the pumps has run intosaid chamber 12 of the arm 10, the weight of the water will tilt thebeam so as to depress the arm 10 and elevate the arm 11, the gate 18 ofthe arm 11 closing by gravity as said arm moves into receiving position,while the contact of pin 19 of the gate of arm 10 forces thelatter-named gate open for discharge of the water from the bucket 13 ofarm 10 through the opening 3 into the reservoir. On such downwardmovement of the arm 10 the water previously drawn through the pipe 27into the pump cylinder 21 is forced out into the pipe 33, as will bereadily understood, while on the upward movement of the arm 11 thepiston in cylinder 22 will move on its suction stroke and draw waterinto said cylinder through pipe 28, ready for discharge into the pipe 33on the suc ceeding downward movement of the arm 11. The tilting of thebeam in the manner described will bring the parts into the positionshown in Fig. 2, in which the arm 11 is brought into receiving positionbeneath the fiume 5, the partition cutting off the flow of water intothe arm 10, whereby when said arm 11 is depressed by the weight of thewater the parts will again assume the position shown in Fig. 1, thewater discharging from the bucket 13 of arm 11, while the pistons in thecylinders 21 and 23 respectively reach the limit of their suction anddischarge strokes and the arm 10 is in position for a repetition of theoperation before described. It will be observed that the construction ofthe chamber 12 of each arm when elevated insures the filling of saidchamber with a body of water of sufficient weight to tilt the beam anddepress said arm. Thus when the descending arm reaches a certain pointin its descent the water will discharge forcibly from said chamber 12over the shelf 16 into the communicating bucket 13, producing a rate offall or impact which increases its motive power. As long as the flow ofwater from the flume continues, the beam will be tilted to alternatelymove the arms thereof into receiving and discharge positions, insuring aconstant supply of water to the pipe 33 for distribution and use.

As set forth, the apparatus may be employed for raising water to anelevation for domestic use or other purposes, and it may be. eflicientlyemployed for elevating water for irrigating portions of land whichcannot be irrigated by ordinary gravital flow from a main source ofsupply.

.. The apparatus may be thrown out of operation at any time by simplycutting ofl the flow of water from the flume, as will be readilyunderstood, for which any suitable type of cut off may be employed.

It will be apparent that the apparatus is simple and inexpensive inconstruction and operation and may be used whenever a source of supplyof flowing of water is available.

Having thus described the invention, what I claim as new is 1. A waterelevating or pumping apparatus, comprising a reservoir, a water supplydevice having its discharge portion arranged above said reservoir, acentrally pivoted rocking beam or lever forming a trough having its armsprovided by a central transverse partition and providing watercompartments respectively diminishing in depth from said partitiontoward their outer ends, the inner ends of said compartments beingarranged adjacent to said water supplying device so as to be alternatelybrought into receiving position beneath the same by the reverse tiltingmotions of the beam or lever, a bucket at the outer end of eachcompartment arranged below the plane of said compartment and having aflaring mouth and a discharge outlet, each compartment being providedwith an inclined shelf at its base projecting partially into the flaringmouth of the communicating bucket, a gravity closing valve controllingsaid outlet and provided with a depending contact portion, and pumpingmechanism actuated by the rocking motion of the lever.
